PHONOGRAPH ATTACHMENT FOR PLAYER-PIAIJOS.

15130550, Specification of Application filed January 3 To all whom it may concern Be it known that I, JACOB SHANKS, a subject of the Czar of Russia, and resident of Louis, Missouri, have invented certain new and useful Improvementsin Phogograph Attachments for Player-Pianos, of

which the following is a specification containing a full, clear,

and exact description, reference being had to the accompanying part hereof.

. My. invention relates to improvements in phonograph attachments for player pianos, and the object of my invention is to construct a phonograph-ic attachment for pianos which is wholly contained the casing of the piano. And a furdriven roll .of the piano player mechanism and the driven shaft of the 'phonographic attachment whereby a uniform speed of the phonograph obtains at all times regardless of the speed changes of .the shaft of the player mechanism. v

With the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawings, 'in which. v

Figure 1 shows fragments of a piano casing with parts broken away to illustrate the relative arrangement of the parts of my phonographic attachment to the player mechanism; Fig. 2 is a fragmental plan of the piano casing partly in section showing the arrangement of the horn or megaphone of the phonograph; Fig. 3 is an enlarged detail front elevation showing'the changeable speed connection between the player mechanism and the phonograph; Fig. eis an end elevation of the parts shown in Fig. 3; Fig. 5 is a longitudinal sectional elevation illustrating the clutch-mechanism employed in establishing or breaking connectionbetween the player mechanism and the phonograph; and F ig; 6 is, a fragmental elevation partlyi in section illustra ing the clutch-operating. device.

Referring by numerals to the accompanying drawings: '1 designates the casing which may be of any ordinary construction of a 1ndicator primarily Letters Patent.

, 191a. Serial no. 810,265.

Arranged within the ordinary cabinet 8 and rotatably mounted in said cabinet is an ordinary driven shaft 9 and an idle. shaft 10, the shaft bemg rotated by the ordinary motor usually the pneumatic type (not shown). On each of the shafts 9 and 10 there are ranged the ordinary spools 11 which sup port ordinary perforated rolls i2. Associated with the player mechanism is a tempo I control and indicator comprising in part the I proper 13. a rod 14 upon which the 1n-d1cator is carried and which is arranged for lateral movements relative to the player mechanism, and a lever 15 for the manipulation of the indicator. All of these parts are or may be of the common and ordinarv construction and arrangement. u

The shaft 9 opposite its end connected with the motor projects some considerable distance through the cabinet 8 and support edupon said projecting end of the shaft is a cone-pulley 16 and secured to and rotatable Withthe cone-pulley is a clutch-member 17.

Referring toFig. 5, it will be noted that there is extended through the shaft 9 a pin 18 which is embraced by the clutch-member in such manner that the clutch-member may rotate independently of the shaft and be held against axial movement relative to the shaft.

19 designates movable clutch-member having diametrically opposite longitudinal slots '20 arranged ,to receive thetends of a pin 21 whereby the .n1ember 1 9 will at all timesrotate with the shaft 9, yet/be free to.

move axially thereof. The movable clutchplayer piano.

member is provided with a circumferentialv flange 22 arranged to be engaged by a d having a bifurcated end 23 and an sii- .lgeu manipulating en 24 for the operation of the movable clutch-member.

25 designates a standard'which with the end of the cabinet. 9 constitutes a support for a bracket 26 in which there is journaled a vertically disposed arbor 27 arranged for the support of a record disk support 28. Carried by the bracket 26 is a pintle 29 and horizontally alining with said pintle and also carried by the bracket 26 is an adjust able pintle 30. Supported by these two pintles is a shaft :31 carrying a cone-pulley 32 end wall of the piano 1 as shown; and described that the which cone-pulley is connected with the cone-pulley 16 by means of a belt 33.

Adjacent the cone-pulley 16 is a bearing 34 in which is pivotally mounted a belt shifter 35 which has its longest arm connected with the rod 14 of the tempo control and indicator.

Carried by the shaft 31 is a bevel gear wheel 36 arranged to mesh at all times with a pinion 37 secured to rotate with the arbor 27.

It is to be observed that the front of the piano casing to one side of the music rol cabinet is perforated or grilled as shown at 38 in Fig. 2, and secured preferably to the casing is a horn or megaphone 39, the open large end of which is next adjacent the perforated or grilled portion of the piano front. The horn has associated therewith 40 and the sound-box 11, both of which last mentioned elements are shown only by dotted lines in Fig. 2.

It will be readily understood from the construction and arrangement of the parts of the player mechanism constitutes the driving neans for the phonograph, and by the arrangement of the cone-pulleys in reverse positions relative to each other and the belt connecting the pulleys that, when the tempo of'the music is changed, the belt will be shifted to one end or the other of the cone carried by the driven shaft of the player mechanism and, for the reason that the cone geared with the verse position relative to the cone-pulley, that the speed of the record support is maintained approximately uniform, thereby causing the record of the the usual pivoted arm single motorcontrol whereby,

record support is in a refirst mentioned phonograph to reproduce at substantially the same rate of speed, at all times, as when the record was made. 4 v

I claim:

1. In combination. with. a player piano mechanism having a graph, means including a reverse cone an tempo control, a phono belt drive connection between the player mechanism and the phonograph whereby, when the tempo of the player mechanism is varied, the speed of the phonograph will be substantially uniform.

2. In combination with a player piano mechanism having a tempo control, a phpnograph, and means including a variable-speed connection between said player mechanism and the phonograph connected with said tempo control whereby, when. the tempo of the player mechanism is varied the phonograph will operate at a substantially-uniform speed.

3. In combination with a player piano mechanism having a tempo control, a phonograph, means including. a variable speed connection between said player mechanism and the phonograph connected with said tempo when the tempo of the player mechanism is varied, the phonograph will operate at a substantially uniform speed, and means whereby said variable speed connection may be thrown in and out of gear.

In testimony whereof, I have signed my name to this specification, in presence 0. two subscribing witnesses.

, JACOB snAnirs.
